While using ekahau cloud it happened to me that the synchronization failed so here in 5 easy steps how to restore Ekahau files directly from the ipad.


1. Connect the ipad to the PC and start Itunes.

2. Use file share to save the Projects folder under the Ekahau app.

3. Open the folder and select which project you want to restore based on date.

4. save this folder as .zip

5. change the file extension to .esx








When I was working with a WLAN PI recently I stumbled upon a program named VirtualHere which allows USB devices to be used remotely over a network just as if they were locally connected. This allowed me to perform spectrum analysis remotely, both on the internal network and on a VPN connection. Actually, the options are endless and only limited to what you connect.



Server Setup:


SSH into WLAN PI

wget https://virtualhere.com/sites/default/files/usbserver/vhusbdarm64
chmod +x ./vhusbdarm64

By default, the WLAN PI blocks port 7575 used by VirtualHere.

sudo ufw allow proto tcp from any to any port 7575

to start

sudo ./vhusbdarm64

options: -b run as daemon in the background -c configuration file -h display this usage -l display license text -i prefer ipv6 (dual/stack) -r log to file instead of syslog


Client Setup:


The VirtualHere USB Client runs on Windows, OSX, Linux and Android.

And can be found here: https://www.virtualhere.com/usb_client_software


Run the client, it will automatically try to connect to the server.



Once you are connected to the server the devices attached to your USB Server are listed and you can right-click those to connect.



When you see that it is used by you, the usb is connected to your pc.





licensing

The trial version of the server will allow you to share 1 device without time restrictions using one of the generic builds needed for the WLAN PI. To share more devices you need to purchase a license.




Are you working on a design in Ekahau Site Survey (ESS) and using a specific AP (Access Point) with different antenna types? In my case, in my existing project file, I had to change all the Access Points to a new type. I made the choice for Aruba 504 + AP-ANT-25A - this is not a direct combination in Ekahau but with a detour. When you assign an AP in ESS, the next time you add a new AP to the map, it uses the earlier AP you had placed.

However, if you customize an Access Point by choosing an AP from the drop-down and changing the antennas to a 3rd party antenna – the next time you want to change it, this is only possible by choosing an ap from the drop down menu. This is a disadvantage if you’re adding plenty of APs, and/or b) switching between various antenna types.

Each time you place an AP, you have to manually go in and make changes to everything - the angles, antenna height, TX power, and - the antennas themselves. You can make changes to the ESS config files for adding APs and custom antennas.

When you edit the “accessPointTypes.xml” file and add the AP with the antennas you want, the antenna might already exist in ESS but it might not be paired with the AP you want to use. This is all you need to fix to make it work.

After fixing it, if you open your project file in ESS, you can see the new customized version of the AP in the list!

Creating Access Points in Ekahau

The following are the steps to create access points yourself in Ekahau:

Step 1

Open C: \ Program Files \ Ekahau \ Ekahau Pro \ conf \

Now, open antennas.zip. copy here from the filename without extension.


You can find both the 2.4GHz and 5GHz antennas you need.






Step 2

Open C: \ Program Files \ Ekahau \ Ekahau Pro \ conf \. Then, open accessPointsTypes.xml with admin rights.

Step 3

Search for your required AP and find it. Next, copy it.


 </accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-1W">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
  <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>

Paste the AP directly under the original AP.


</accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-1W">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
  <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>
</accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-1W">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
  <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>

Step 4

Change the red highlighted data using the previously selected AP from step 1.


 </accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-1W">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
  <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>
</accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-1W">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-1W 2.4GHz" defaultAntenna5="Aruba AP-ANT-1W 5GHz"/>
  <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>

The below will get displayed in my case.


</accessPointType>
 <accessPointType vendor="Aruba" model="AP-504 + AP-ANT-25A">
 <radioType technology="ax" frequencyBand="2.4" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-25A 2.4GHz 5dBi" defaultAntenna5="Aruba AP-ANT-25A 5GHz 5dBi"/>
 <radioType technology="ax" frequencyBand="5" mimo="2x2" spatialStreams="2" defaultAntenna24="Aruba AP-ANT-25A 2.4GHz 5dBi" defaultAntenna5="Aruba AP-ANT-25A 5GHz 5dBi"/>
 <radioType radioTechnology="bluetooth" frequencyBand="2.4" defaultAntennaBluetooth="Aruba AP-505 BLE"/>

Save the file.

Step 5

Open Ekahau. Now, you can find your created antenna.


You can edit the config files for APs and antennas so you can create custom AP/ANT to use in all your projects. Don't forget that you need admin rights if you want to edit anything in the folder. Also backup this file as well,this will be rewritten with the next update.
